SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 296,203, dated April 1, 1884.

Application flied November 9, 1883. (No model.)

To all whom it may concern Be it known thatI, J OHN T. MEAD, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and usefnl Improvements in FeedVater Purifiers; and I do hereby declare the following to be a fuli, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the saine.

My invention relates to feed-water purifiers; and-it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

The object oi' my invention is to improve a device on which I have already obtained Letters Patent for the United States, dated April 24, 1885, No. 276,139.

In the drawing, the figure is an elevation, partly in section, of my improved feed-water purifier.

A represents the shell of the purifier; B,the boiler; C, the steam-pipe leading from the boiler into the purifier; I), the'feed-water pipe leading from the purier to the boiler, and. Ethefeed-water-supply pipe, leading, usually, from a heater (not shown) to the purifier.

The shell Ais provided with two perforated plates, c and c', between which is placed the filtering material, and a hand-hole and plate at c?, leading into the filtering-chamber A.

F is a funnel. the upper edge of which joins the shell A, and is secured thereto, forming a tight joint. The lower end is attached to the pipe j',that extends through the iiteringchamber and into the settling-chamber O. The steani-pipe G is provided inside of the purifier with the conical disks c and c', in the position shown, and has perforations for admitting steam between the conical disks. It will be observed that the discharge of the pipe E is directly over the center of the upper disk.

In operating the device, the live steam, as aforesaid, is admitted through the pipe C between the conical disks. At the Sametime the feed-water, usually in a more or less heated condition, is admitted through the tube E, and, falling on the cover c, spreads in a thin sheet over the cover and receives considerable heat from it. As the water passes from the bottom of the cover, it cornes in direct contact with the steam, and is thereby heated to the precipitating-point, and, passing through the funnel E and the pipe f,is discharged into the chamber O, when most of the impurities are precipitated, and may be removed through the pipe P. The water then rises through the ilteringchamber,where any Heating particles are arrested, and from above the iilteringchamber and below the funnel F the water passes through the pipe D into the boiler Vhat I claim isl l, In a feed- Waterpuriier, the combinatie oftwo conical disks, with asteam-pipe arranged to admit steam between the disks, and ai'eed.- water-supply pipe arranged to discharge the feed-water upon the apex ofthe upper conical disk, substantially as set forth.

2. The combination, with a cylinder divided into two parts by two perforated diaphragins, between which is packed suitable filtering material, the funnel located above the upper diaphragm, and the pipe connected to the funnel and terminating below the lower diaphragm, of the steam-inlet pipe and the conical disks secured thereto,respectively, above and below the escape-openings, the water-supply pipe terminating directly above the center of the upper conical disk, and a water-discharge pipe situated below the upper edge of the funnel, substantially as set forth.

In testimonyT whereof I sign this specification,in the presence of two witnesses, this 27 th day of October, 1883.

- JOI-IN T. MEAD.
